Pretty busy at work. Stayed back a short time at night and completed stock sheets. Played piano at night for Charlie and tried some new songs through. Got on pretty well. Finer day, but still stormy. Received news that submarine B.11 had blown up Turkish ship “Messudiyeh”1 in the Dardanelles. Lieutenant Commander Norman D Holbrook2. He passed under 5 chains of mines to do it.
